A 45-year-old female presented with gross hematuria. Right renal arteriovenous malformation on abdominal contrast-enhanced computed tomography necessitated urgent transcatheter arterial embolization. Right renal digital subtraction angiography revealed a single tortuous and dilated vessel converging to an aneurysmal dilated vein. To selectively embolize the malformation, we closed the arterial side with a microballoon and attempted glue embolization; filling occurred unexpectedly early, and another balloon on the vein side helped control the renal vein blood flow. Glue embolization was performed without adverse events. Glue embolization for high-flow arteriovenous malformation under balloon occlusion-mediated inflow and outflow control can effectively and safely embolize complete target vessels.
一名45岁女性出现肉眼血尿。腹部增强计算机断层扫描显示右肾动静脉畸形,需要紧急经导管动脉栓塞术。右肾数字减影血管造影显示一条单一的迂曲扩张血管汇入一个动脉瘤样扩张的静脉。为了选择性栓塞畸形,我们用微球囊封闭动脉侧并尝试进行胶水栓塞;意外地很早就发生了填充,静脉侧的另一个球囊有助于控制肾静脉血流。胶水栓塞术顺利完成,未出现不良事件。在球囊闭塞介导的流入和流出控制下,对高流量动静脉畸形进行胶水栓塞可以有效且安全地栓塞完整的目标血管。
